结构体的问题

Question

代码typedef struct {
JITASYA_JYUSIN_DATA JitasyaJyusinData;
char sJyusinDate[10];
char sJyusinTime[12];
char dHouseiIdo[4];
char dHouseiKeido[4];
double iDistanceLine;
double iDistanceX;
double iDistanceY;
double dSoutaiHoui;
int iZone;
long dTsusinErrCount;
}JITASYA_JYUSIN_DATA1,*pJITASYA_JYUSIN_DATA1;                
调用时
void s1(JITASYA_JYUSIN_DATA1 CacuMonit[])
{
strcpy(CacuMonit[0].dHouseiKeido,"56");
strcpy(CacuMonit[0].dHouseiIdo,"78");
strcpy(CacuMonit[1].dHouseiKeido,"bb");
strcpy(CacuMonit[1].dHouseiIdo,"445");
}void main()
{
JITASYA_JYUSIN_DATA1 CacuMonitor[2];
strcpy(CacuMonitor[0].dHouseiKeido,"12");
strcpy(CacuMonitor[0].dHouseiIdo,"fv");
strcpy(CacuMonitor[1].dHouseiKeido,"33");
strcpy(CacuMonitor[1].dHouseiIdo,"3442");
// s1(CacuMonitor);
cout<<CacuMonitor[0].dHouseiKeido<<endl
<<CacuMonitor[0].dHouseiIdo<<endl
<<CacuMonitor[1].dHouseiKeido<<endl
<<CacuMonitor[1].dHouseiIdo<<endl;}
使用s1(CacuMonitor);输出式正常的。
使用上面的代码strcpy(CacuMonitor[1].dHouseiKeido,"33");输出式空的其他的事可以的

Answer 1

你这只分配了指针，没有分配内存呀，用new分配
JITASYA_JYUSIN_DATA1* CacuMonitor=new JITASYA_JYUSIN_DATA1[2];
delete[] CacuMonitor;

Answer 2

如果正确strcpy(CacuMonitor[1].dHouseiKeido,"33");
cout<<CacuMonitor[1].dHouseiKeido<<endl；输出应该是 33
可是输出 是 空的
但是使用自己定义的函数s1(CacuMonitor);输出是正确的。
问题出在哪儿，实在看不出来

Answer 3

strcpy(CacuMonitor[1].dHouseiIdo,"3442");
越界了，"3442"为5个字节，直接改了dHouseiKeido

Answer 4

strcpy(CacuMonitor[1].dHouseiIdo,"3442");
越界了，"3442"为5个字节，直接改了dHouseiKeido

Answer 5

Jarrylogin的改法试过了，还是老样子
